As I have said on this Blog, I am numbers person. Figures tell everything and trend-lines explain what has happened, what might or will happen.
Wondering what is happening.
Out of my natural curiosity, I have started plotting past solar indices in order to get an indication of what our next Solar Cycle (25) might look like.
Recently it was announced by a Space Weather Meteorologist, Tamitha Skov
( https://www.youtube.com/user/SpWxfx https://twitter.com/TamithaSkov )
that the first sunspot for Cycle 25 had appeared.
Once I thought about it, I looked at the most recent Solar Flux plot of Cycle 24. It certainly appeared that it was dropping rapidly. I thought it could be contrary to prediction that our next solar cycle would be worse than this one.
once these cycles started its end.
The Mathematical term is slope.
The only hitch to this analysis is a constant elevated level of geomagnetic activity. Although solar activity has declined since 2014, geomagnetic activity has not. The values have actually increased somewhat and still flare up now and then.
I have looked at numbers and charts for over 40 years to identify patterns and trends.
